T all whom t may concern Be it known that I, ALBERTK; Renner-11s,: `a citizen of the United States of America,

and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Spacing-Sleeves, of which the following is a chine.

specification.

This invention relates to means for positioning polishing wheels and the like on their carrying spindles in any adjustable manner in order to attain any required location of the wheel beyond the headstock of the machine, and the object of the present improvement is To provide a simple and efficient structural formation and combination of parts in a telescopic? spacing sleeve for insertion between the usual fixed collar 0f the carrying spindle and the polishing or other wheel, said sleeve being adapted to be extended or contracted to a required length and be locked at such point of adjustment so that when in its interposed condition, the required amount of overhang of the polishing or like wheel at the side of the headstock of the machine will be attained in an effective and substantial manner, all as will hereinafter more fully appear.

. In the accompanying drawing Figure 1 is a longitudinal sectional elevation, illustrating the general arrangement of parts in the present improvement.

Fig. Q, is a detail side elevation of the spacing sleeve. Like reference numerals indicate like parts in both views.

Referring tothe drawing, 1 designates a portion of the headstock in which is mounted the live spindle of a polishing or like. ma-

Said spindle is formedl with the usual screw threaded louter portion and has the usual vfixed abutment collar or enlargement 3 inside of said screw threaded outer portion asshown.

` t, 5 designate the usual collars loosely fitting the spindle 2, and between which the hub portion of a polishing or like wheel 6 is inserted and held in place by the clamping nut 7 having screw threaded engagement with the aforesaid screw threaded `outer portion of the live 'spindle 2 as shown. The construction s0 far described is usual to polishing and like machines and the present improvement involves in connection herewith, an adjustable spacing sleeve yadapted to position the polishing or like wheel 6 at difspeeieauon of Letters Patent.

ferent distances 4away fromthe headstock 1 .of theniachine and so'as to attain efficient operation on diierent classes of work, and to such end involves a detail :formation and arrangement of parts as follows S and 9 designate sleeve sections formed to telescope one within the other, with the inner sleeve section 9 having a sliding fit upon the live spindle 2 of the machine. Said sleeves are provided with any usual interengaging means whereby they are locked together at the adjustment or extension of one sleeve section inrelation to the other, said means preferably comprising parts as follows:

10 designates a longitudinal slot formed in the outer sleeve 8 and having two series of lateral notches V11 arranged in alternated or staggered relation as shown.

12 `designates a pin or stud xed on the inner sleeve 9 and having a longitudinal sliding movement in the slot 10 aforesaid, in the operation of adjusting or telescoping the sleeve section 8, 9, and adapted to be moved laterally into a neXt adjacent lateral notch 11 to lock said sleeve section at the required adj ustment.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with the screw threaded live spindle and fastening nut of a polishing machine or the like, of a spacing sleeve adapted to fit between the fiXcd collar of the live spindle and the usual wheel holding collar, said spacing sleeve comprising two sections formed to telescope together, and means for securing said sections at different relative adjustments substantially as set forth.

2. The combination with the screw threaded live spindle and fastening nut of a polishing machine or the like, ofv a spacing sleeve adapted to lit .between the fixed collar of the live spindle and the usual wheel holding collars, said spacing sleeve comprising two sections formed to telescope together,

ioo

shing machine or the like, of 'a spacing in the outer section, lateral notches arranged sleeve adapted to t between the xed collar in staggered relation and opening into said 10 of the live spindle and the usual Wheel holdslot, and a fixed stud on the inner sleeve ing Collars, said spacing sleeve comprising section, substantially as set forth.

5 two sections formed to telescope together, Signed at Chicago, Illinois, this 15th day and means for securing said sections at diof August, 1918. ferent relative adjustments, the adjusting sleeve comprising a longitudinal slot formed ALBERT L. RADLEIN.
